View Full Version : Torque specs for oil feed/return line banjo bolts

I was hoping someone could tell me the torque specs for the banjo bolts (2 each) on both the oil feed and return lines for the turbo. I found some evidence of seeping around the lines and just to be safe I am replacing the washers, seals, and banjo bolts on both of them when I get my car back. There is a slight chance it is there from the last oil change but I doubt it since it would have to drop just right to get where it is and not anywhere else. Plus I can see it on the bottom of the turbo where the return line starts. Any help is greatly appreciated.

I apologize as I don't have any useful information to contribute to your inquiry, but shouldn't this be a warranty issue worth looking into if this is the case?

My car is well past bringing it in for this. I wouldn't feel like putting it back to stock and there are quite a few things they could say were the cause. It was like $40 for all the parts anyways and I don't mind doing it.

Understood. It really would be nice if someone leaked the Fiat tech repair manual for these vehicles the way I've seen it happen in many other car communities (legalities aside, it's a tremendous resource to have). It would be a real help for the D-I-Yers that would like to rely on official literature. Hopefully someone has the answer for you, otherwise I'd try bugging a Fiat tech (if someone at your local dealership lets you get close enough to one without asking too many questions).

There are a couple people on here that probably have the specs. I'm sure they will chime in.

Let's not incourage that, though.angelgrin We have a good relationship and don't want to hurt that. The manual is now available and isn't really that much, especially compared to the factory Audi manuals I've bought.
